Abstract
Vehicles often collide with bridges. However, there are no available guidelines for bridge inspectors to assess damage and to make repair decisions. This project addresses this gap by investigating the behavior of steel girder bridges subjected to vehicular collision through (1) performing non-destructive field testing, (2) developing validated numerical models, and (3) performing parametric investigations to extend research findings. Field testing was performed using Digital Image Correlation (DIC) - a portable, non-destructive, photographic measurement technique. The focus was on two- and three-span continuous multi-girder steel bridges for which an exterior girder has sustained Category T damage, i.e., torsion about the longitudinal direction. This project can benefit Indiana Department of Transportation (INDOT) business processes by potentially reducing the number or amount of repairs, leading to cost savings and longer lifespans for bridges.
